. Toall whom it may concern."

Be it known that I, SAMUEL A. PRITCHARD, a citizen of the United States,residing at Van Meter, in the county of Dallas, State of Iowa, haveinvented certain new and useful Improvements in Throttle-Controllers forAutomobiles; and'I do herebydeclare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to .which it appertains to make and use the same.

This invention relates to a throttle cona controller that can beoperated either by foot power or by hand power.

The object of the invention is to providea throttle-controller having animproved construction embodying simplicity, efliciency,

low cost of manufacture, and which can be,

easily associated with standard automobiles and particularly a Fordautomobile.

With the above and other objects in view the invention consists in thedetails of construction and in the arrangement and combination of partsto be hereinafter more fully described and particularly pointed out inthe appended claim. V 'In describing the invention in detail referencewill be had to the accompanying drawings wherein like characters ofreference denote corresponding parts in the several views, and inwhich'- Figure l is a plan view of a fragment of an automobile showingthe improved throttle controller applied;

Fig. 2, a side viewof what is shown in Fig. 1; and

Fig. 3, a section on the line 3-3 of Fig. 1. Referring to the drawings Aindicates generally an automobile which includes the usual motor 10,carbureter 11, transmission casing 12, steering column 13, steeringshaft 14, and hand operated throttle controlling shaft 15 mounted on thesteering column 13 and provided with the usual arm 16.

he improved throttle controller embodies s'paced bearings 17 mountedupon the transmission case 12 and having rotatably mounted therein anoperating shaft 18 having fixed thereon a pedal lever 19 so positionedas to be'readily actuated by the foot of the driver when desired. Oneend of the shaft 18 has fixed thereon an arm 20 and pivotally connectedto the free end cured the bell crank throttle lever open 1 of the arm 20is one end ofa link 21, a

cotter pin 22 being utilized to prevent disengagement of the link 21from the arm 20. Secured to the cotter pin 22 is one end of a spring 23,the other end of which is se-' to the transmission casing 12. This sprin23 serves to normally hold the throttle o the carbureter 11 in closedposition, said throttle, of the carbureter embodying 24.. The .end ofthe link 21 remote from the arm 20 is pivotally connected to one end ofthe lever '24. A pivot pin 25 having an eye head 26 is mounted in theother end of the lever 24 and in said eye'is slidably engaged a rod 27.The end of the rod 27 remote from the lever 24 is pivotally connected tothe arm 16 at 27 in any suitable manner for operate the throttle of theoarbureter 11 to osition. Sliding movement of the when opening thethrottle of the carbureter is limited by'a cotter pin 28 engaging thehead 26. Encircling the rod 27 and having one end fixed to said 'rod andits other end bearing against the head rod 2 .26 is a spring 29 whichassists in returning the'parts to their be obvious.

In operation of the device it will be apparent that when the pedal lever19 is pressed down with the foot the shaft 18 will be rotated and thisrotation of said normal position as will 'shaftwill be transmittedthrough the link 21 tothe throttle lever 24.- to impart opening movementto the latter. During this opemng movement of the lever 24'the pivot rod27 against 29 so that said with the foot pin 25 will slide along the theinfluence of the spring rod 27 will not interfere operation of thedevice.

What is claimed is In an automobile the combination of a motor, acarburetor including a throttle lever, a transmission casing, a steeringcolumn, a handle throttle shaft mounted on the steering column, an armon said shaft, a shaft rotatably mounted on the transmission casing, afoot lever fixed to the second A shaft, an arm on the second shaft, aspring connecting said arm to the transmission casing, a link having oneend connected to the armon the second shaft and at its other endconnected to the throttle lever, a pivot actuation by rotation of theshaft 15 to pin carried by the throttle lever, said pivot ment of therod in one direction with repin including an eye head, a rod havingspect to the eye head.

In testimony whereof, I 'aflix my signaone end slidably engaged in theeye head and its other end connected to the arm on ture, in the presenceof two Witnesses.
